So I'm not sure if this is just something specific to my mod loadout or what, but it's driving me just a little bit nuts. Seemingly at random, paired loaders (moving from one chest to another chest) will change orientations and get into a broken state.

When I try to rotate them back to the way they should be, instead of flipping orientation they actually rotate like normal loaders. A row of ten loaders pulling from chests and ten loaders going into chests will become a mixed up mess of random directions which can only be fixed by removing and replacing all the loaders.

I think I might swap to a different implementation of loaders soon honestly, only because this is driving me nuts. Science stops working, so I spend three minutes looking through the factory to find out that loaders which are moving copper cables suddenly decided to flip around to face each other or something.

Unfortunately, I haven't been able to pin down precisely what causes this! I'm sorry it's not a more helpful error report. I'm using 0.12.0 of the mod in a setup I put together based on K2SO, but unfortunately, this issue only seems to happen when I'm not looking at loaders, and then it takes a while for the effects of whatever just broke to be felt down the line for me to notice it.
